In 18th-century drydock ship construction, which risk increases most when timber seasoning falls below optimum levels before planking?

💡 Explanation

Increased hull twisting occurs because inadequate timber seasoning causes uneven wood shrinkage across planking after assembly and repeated wetting. This induces internal stresses throughout the hull because constrained shrinkage generates cumulative twisting forces, rather than uniform stress. Therefore, hull integrity decreases.
